1062 | for details. YYERROR is fine as it does not invoke this |
1063 | function. |
1064 | - If this state is a consistent state with a default action, then |
1065 | the only way this function was invoked is if the default action |
1066 | is an error action. In that case, don't check for expected |
1067 | tokens because there are none. |
1068 | - The only way there can be no lookahead present (in yychar) is if |
1069 | this state is a consistent state with a default action. Thus, |
1070 | detecting the absence of a lookahead is sufficient to determine |
1071 | that there is no unexpected or expected token to report. In that |
1072 | case, just report a simple "syntax error". |
1073 | - Don't assume there isn't a lookahead just because this state is a |
1074 | consistent state with a default action. There might have been a |
1075 | previous inconsistent state, consistent state with a non-default |
1076 | action, or user semantic action that manipulated yychar. |
1077 | - Of course, the expected token list depends on states to have |
1078 | correct lookahead information, and it depends on the parser not |
1079 | to perform extra reductions after fetching a lookahead from the |
1080 | scanner and before detecting a syntax error. Thus, state merging |
1081 | (from LALR or IELR) and default reductions corrupt the expected |
1082 | token list. However, the list is correct for canonical LR with |
1083 | one exception: it will still contain any token that will not be |
1084 | accepted due to an error action in a later state. |
